Why Choose The SDA

Why Join?


All SDA resources and expertise are exclusively for the benefit of members. If something goes wrong at work and you’re not an SDA member.....we can’t help you! Your membership commences upon acceptance at the monthly Committee of Management meeting and remains valid, subject to the Rules of the Union, for such time that you remain financial and fees are deducted from your pay and remitted to the Union. If you cease to work for whatever reason and your employer is no longer deducting fees on your behalf, it is your obligation to notify the Union. The Union reserves the right to terminate your membership if you have not paid membership fees for 3 months or more, unless you have applied and been granted an exemption under The Rules of the Union.
